JL Audio VX1000/1i
Mono subwoofer amplifier with digital signal processing — 1,000 watts RMS at 2 ohms


Amplifier and DSP
JL Audio's VXi Series amplifiers combine JL Audio's latest amplifier technology with killer signal processing. JL Audio teamed up with AKM™ to create this customized processor-amp hybrid. They also improved the amp's Class D performance by shortening the signal path, placing the output capacitor banks closer to the outputs, and using DirectFET® MOSFET output devices, resulting in higher efficiency, and audio quality.

1,000 watts to your bass
The VX1000/1i mono subwoofer amplifier can kick out up to 1,000 watts RMS for your sub, and sports 3 channels of digital signal processing. You could set up a system, for instance, by routing the signal from the receiver to this sub amp first, and then sending a processed stereo signal on to a separate amplifier for your other speakers.

Digital precision
The 24-bit 96 kHz processing for each channel includes signal routing and mixing, 10-band parametric EQ, time-alignment, Low-pass and high-pass filters, and 0.1 dB precision output level control. Along with tuning the audio signal, the processor provides a master clock signal for the Class D amplification.

Remote control
You make all your settings and adjustments from your compatible device running JL Audio's TüN™ software.
